It is a colorless liquid with a density of 1.42 g/cm3 and a boiling point of 120°C at 0.1 mmHg. Methylphosphonsaeure-(2,4-dichlor-benzylester)-methylester is a derivative of methylphosphonic acid, where the hydroxyl group is replaced by a 2,4-dichlorobenzyl group and a methyl group. It is used in the synthesis of various organophosphorus compounds and as a precursor in the production of pesticides and chemical warfare agents. Due to its potential hazardous nature, it is essential to handle Methylphosphonsaeure-(2,4-dichlor-benzylester)-methylester with proper safety measures and precautions.
The CAS Registry Mumber 5849-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5849-81: (6*5)+(5*8)+(4*4)+(3*9)+(2*8)+(1*1)=130 130 % 10 = 0 So 5849-81-0 is a valid CAS Registry Number.
